and useful. Improvements inl Loose -=Leaf.

Ledgers and Binders; and I do hereby declare that the following is a full, clear,.and exact description of the same.

This invention relates particularly to 10 loose-leaf ledgers of the type having telescopic bind'in -posts and it has for its object to provide'a edger adapted to clasp theremovable leaves more tightly and to be more easily andunilormly manipulated and more durable than loose-leaf ledgers of this type.

heretofore used.

The invention may be said briefly to con- ,sist of a rotary locking device, in combination with non-rotatory part adapted 'to coact therewith and automatically lock the retaining-bars against displacement away from one another in any position to which they nlilay be moved to clamp the leaves between t em.

Another feature of the invention is means whereby the locking device is held 0r after I having been moved or released by a key retained in such position until the key is withdrawn; and the invention further consists of 30 means for distributing the pressure uniformly throughout the retaining-bars at wllilaatever point along said bars it may be ap- ,p e

For full comprehension, however, of my invention reference must be had to the accompanying drawings, forming a part ofthis specification, in which similar reference charactors-indicate the same parts, and wherein Figure 1 is a top view of my improved 4oloose-leaf-ledger binder. Fig. 2 is a similar viewwith the top plate removed and illustrating particularly the means for locking the clamping-bars of the device in any position to which they may be moved. "Fig. 3 is a face view of my improved binder, and Fig. 4

is a longitudinal sectional view of the central binding-post of my improved binding means. Fig. 5 is an enlarged transverse vertical sectional view.

A pair of clamping-bars b b have a pair of metal plates 0 0, adapted -to overlap one another, secured rigidly thereto. These plates are preferablybent to present top and bottom c and 0 respectively, back a, and ends 0 A pair of telescopic tubes (1' and 6, respectively, are secured rigidly to theclampingscopic post and ierotatably carried by the clamping-bar b,-and a pair of lugs m, mounted rigidly uppn the inside of the tube e, engage in the t ead of this worm and cause the same to rotate when the clamping-bar carrying the said worm is moved toward and from the other clamping-bar. A gear-Wheel n is mounted rigidly u on the outer end of this worm, which eXten s through the clampingbar 12, carrying the same, and said gear intermeshes with a second ear 0, mounted rigidly upon a stub-spind e .0, carried by the clampingbar I), while distance-pieces p establish thespace between this clampingbar I) and the inclosing plate 0 to accommodate the gears n and 0. A ratchet-wheel g is mounted rigidlyupon the upper end of spindle 0, and the teeth thereof are adapted to be engaged by a pawl 1", pivoted upon the upper end of the worm, upon which is also pivoted a lever s of substantially bell-crank form, and one arni whereof is provided with a laterally-projectinglug 8', adapted when the lever is moved in one direction to engage the pawl and move it out of engagement with the teeth 'of the ratchet-wheel, while the end of such arm is notched, as at 8 to fit upon and be stopped by a stop if when the lever is moved in the opposite direction, which movement releases the pawl and allows it to be thrown by a bow-spring u into en agement with the teeth of the ratchet-whee The clampingbars b b are caused to con stantly lie parallel to one another whatever their distance ma be away from one another and a pressure it exerted u on one end is distributed throughout same y a pair of toggle-bars 2, pivotally connected together, as at 3, and theends of'the said bars. at one end of the device are pivotally connected to a pair of lugs 4, carried rigidly by the clamping-bars, while their opposite ends are connected slidably to a pair of rigid lugs carried upon the opposite endsof the clamping-bars and slotted, as-at 6, to receive-apair of studs 7, carried rigidly by the said opposite ends of the toggle-bars to effect a sliding connection therebetween'and the said lugs Operation: The key is first inserted through a keyhole 8 i'n the cover 9 and into a recess or aperture 10 of segmental form in the lever s and uponbeing' turned in a direction toward the ratchet-wheel will displace the pawl from the latter and? allow theworm freedom to rotate in a' direction to allow the clampingba'rsto move away from oneanother'under the influence of a pair of expansile helical springs 11, located in the telescopic bindingpostsand 7t V The leaves are then placed u on the'binding postsand the key turned-in t ewoppositedirection, thereby again causing the pawl to engage-the teeth of the ratchetwheel and preventing the same and the worm rotatingih the direction to allow the clampingbars to move away from: one another, but at the same timeallowingthe said clamping-barsto be pressed toward one another; which is then done until the leaves put place are clamped tightly, in which manto be inserted into the lirst-mentioned tube and receive the worm therein, a pair of pins carried rigidly by opposite sides otthe interior oi'the last mentioned tube and adapted to engage the thread. of such worm and cause the rotation thereof in one direction or the other accordingly as the bars are moved toward or from one another, the said worm heing otherwise free of the interior of the tube in which it is located, locking means carried partially by the bar which carries the worm and partially by the worm and adapted to retain the worm against rotation in one direction or allow the same freedom to rotate in both directions, for the purpose set forth.

A binder for a loose-lea'f'led ger, oonsist' ing of a pair of clampingrbars, means for limiting the movement" of said bars away from one another and for guiding the same in their movement, of a worm carried rotatably by other bar and having a lug thereon adapted to engage the thread of said worm-and rotate the latter in either direction according to Whether the bars are being moved toward or from one another, a gear-wheel mounted one of said bars, means secured'to the seams rigidly upon said worm in close roximity to the clamping-bar carrying the atter, a second gear-wheel interme shing with the firstmentioned gear-wheel, a spindle rotatably supported by said last-mentioned clampingbar and having the second-mentioned gearwheel mounted rigidly upon "one end thereof, a ratchet-wheel mounted rigidly upon the opposite end of said spindle, a' spring-pawl pivoted upon the Worm and engaging the teeth of said ratchetwheel, a lever I fulcrumed upon the worm and adapted when moved in one direction to shiftthe said awl out of engagement with the teeth 0 the ratchet-wheel and when moved in the opposite direction to allow of such engagement, substantially as described and for the purpose set forth.
